This is a Mini Super Capacitor Real-Time Clock module, designed for the Raspberry Pi. It can be used with an Arduino too!
This accessory plugs on top of your Pi's GPIO pins and contains a clock chip and a super-cap that allows your Raspberry Pi to remember the time!
The module uses a DS3231 chip which can be coded to have an alarm function (you can see some discussions on this here
, and there are plenty more on the internet too)
